γ射线辐照对四种蔬菜叶片SOD活性和MDA含量影响的回归分析
REGRESSION ANALYSIS OF γ-RAY EFFECT ON SOD ACTIVITY AND MDA CONTENT IN FOUR VEGETABLE LEAVES
【摘要】 本研究采用曲线拟合、建立相应回归数学模型的方法 ,定量地描述了γ射线对蔬菜叶片中SOD、POD活性和MDA含量影响的动态过程 ;通过对上述动态方程参数的求解与分析 ,4种供试蔬菜对电离辐射的敏感性依次为落葵、莴苣和生菜、青菜。
【Abstract】 Dynamic effects of γ-ray on SOD, POD activities and MDA content in leaves of four vegetable varieties were studied.The results were quantitatively discribed by the method of curve fitting and establishing mathematical model.The parameters of the formula suggested that the four vegetable varieties’ sensitivity to radiation appeared as following order:Basella rubra>Lactuca sativa>Lactuca sativa spp>Brassica Chinensis.
